The anterior temporal lobe (ATL) plays a prominent role in models of semantic knowledge, although it remains unclear how the specific subregions within the ATL contribute to semantic memory. Patients with neurodegenerative diseases, like semantic dementia, have widespread damage to the ATL thus making inferences about the relationship between anatomy and cognition problematic. Here we take a de...

Embodiment has highlighted the importance of sensory-motor components in cognition. Perception and memory are thus very tightly bound together, and episodic and semantic memories should rely on the same grounded memory traces. Reduced perception should then directly reduce the ability to encode and retrieve an episodic memory, as in normal aging. Multimodal integration deficits, as in Alzheimer...

Recent advances in geospatial technologies have made available large amount of geospatial data. Meanwhile, new developments in Internet and communication technologies created a shift from isolated geospatial databases to ad hoc networks of geospatial data sources, where data sources can join or leave the network, and form groups to share data and services. However, effective integration and sha...

Semantic memory was investigated in 27 individuals with schizophrenia and 30 healthy controls using an animal similarity judgment and organization test with reduced retrieval demands. Participants arranged 12 common animal names according to similarity on a computer screen and provided verbal descriptions of organizational strategies. Distance between each animal pair was compared to the number...

Research on normal aging often shows a general slowing in processing speed that has been interpreted to reflect declining cognitive abilities. Here, we challenge this assumption and disentangle age-related alterations in automatic (less attention-dependent) and controlled (attention-dependent) word retrieval in semantic memory. Therefore, an automatic semantic priming paradigm was conducted. Tw...

traditional and modern vocabulary instruction techniques have been introduced in the past few decades to improve the learners’ performance in reading comprehension. semantic mapping, which entails drawing learners’ attention to the interrelationships among lexical items through graphic organizers, is claimed to enhance vocabulary learning significantly. however, whether this technique suits all...

abstract the word science has gone through semantic change in different historical periods and in relation to the cultural and social circumstances of the time and thus has been used in various senses. a semantic study of word in the pre- and post-islamic eras will reveal that the word has been used in different and even opposite senses. this means that, in the age of ignorance (pre-islamic era...

BACKGROUND Semantic and inferencing abilities have not been fully examined in children with communication difficulties. AIMS To investigate the inferential and semantic abilities of children with communication difficulties using newly designed tasks. METHODS & PROCEDURES Children with different types of communication disorder were compared with each other and with three groups of typically ...
